CARBURETER.

SPECIFICATION forming part of Letters Patent No. 238,141, dated February 22, 1881.

Application filed september 2s, man. (No model.)

To all 'whom 'it may concern :V

Be it known that we, WILLIAM MGKENZIE and JAMES H. MASON, of Detroit, Wayne county, Michigan, have invented an Improvement in Carbureters, of which the following is a specification. y

The nature of this invention relates to certain new and useful improvements in carbureters, through which air is forced through chambers filled or partially lled with naphtha or other hydrocarbons to produce an illumihating-gas.

It frequently occurs that occupants of adjoining buildings join in the purchase of a carbureter and appliances for joint use; and it frequently occurs that some of the occupants become dissatisfied because others use more tb an their equal share of the gas, while not bearing a proportionate amount of the expense in producing it. To obviate this difficulty an attempt has been made to use the gas-meters of ordinary construction, so that the proportion of the common expense which each is to bear in running the carbureter may be accurately determined. This in practice has been found y inefficient, for the reason that the hydrocarbon vapors with which the air is carbureted destroy the diaphragm of the meters and render them useless.

The object of our invention is to meet this difliculty by providing, within a common shell, a series of carburetingchambers, to each of which the air is fed from a common air-pump or other air-forciu g device, and from each there is a separate outlet for the gasone being designed for each consumereach being required to keep the carbureting-ehamber allotted to him charged with liquid hydrecarbons at his individual expense.

Figure lis a perspective view of the improved carbureter with portions of the shell broken out to show the series of carburetingchambers and the arrangement of gaspipes leading from`thechambers. This View also shows the common air-chamber which is attached to the common air-pump and the arrangement of air-pipes, one of which leads from said air-chamber (partially broken away) to each of the carbureting cells or chambers. Fig. 2 is a plan view of the same with the top of the shell removed, showing the shape ofthe preferred carburetin g cells or chambers.

In the accompanying drawings, which form a part of this specication, A represents a scroll-shaped cell or carbureting-chamber to receive the liquid hydrocarbons. cells are constructed as desired, and placed within a common shell, B, each cell having no communication with the others. Each cell is provided with an ainpipe, C, its outer end terminating in the common air-chamber D, into which air is forced to lind access to the several chambers to each through its appropriate air-pipe. Each of the cells is also provided with an escape-pipe, E, to which proper gaspipes are attached to convey the gas to the various consumers. These pipes E may also be utilized to ll the cells with the liquid hydroearbons, and each of the joint users ofthe common device furnishes to his particular cell such liquid hydrocarbon as he desires to utilize at his own expense.

What we claim as our invention is- 1. A carbureting apparatus consisting of a series of indepen den t carb uretin g-cell s inclosed within a common shell, each cell being provided with a separate air-inlet pipe opening at the outer end into a common chamber, into which air is forced, substantially as and for the purposes set forth.

2 The combination, with a series of independent carbureting-chambers, each inclosed within a common shell and each provided with a separate air inlet pipe connecting at its outer end with a common air-chamber, of a series of gas-outlet pipes, one communicating with each chamber, substantially as described, and for the purposes set forth.
